CRISPR library is a high-throughput gene screening method established based on CRISPR/Cas9 technology. It identifies phenotype-related genes or screens new drug targets through functional screening, enrichment and deep sequencing analysis. The scope of screening can be the whole genome, a certain gene family, or a certain signal pathway gene. CRISPR library screening has become the preferred platform for large-scale gene function screening benefited from the characteristics of CRISPR/Cas9 such as versatility, low noise, high knockout efficiency, and less off-target effect.
Focusing on gene editing and having rich experience in cell line gene editing, Ubigene can provide 8 major libraries and one-stop services including sgRNA library construction, virus packaging, cell transfection, antibiotic screening, NGS sequencing, and data analysis.
Ubigene provides one-stop services for CRISPR-KO, CRISPRa and CRISPRi customized libraries, including sgRNA library construction, virus packaging, cell transfection, antibiotic screening, high-throughput sequencing and data analysis. We offer multiple deliverables meet different research needs.
Including gRNA design, chip synthesis, plasmid construction, plasmid extraction and NGS validation (coverage>99%, uniformity < 10)

Ubigene's off-shelf whole genome CRISPR library of human and mouse can achieve high throughput and rapid screening of functional genes of the entire genome. The human whole genome CRISPR libraries include the single plasmid system (gRNA and Cas9 are in the same plasmid) and the dual plasmid system (gRNA and Cas9 are in different plasmids). At present, only single plasmid system of the mouse whole genome CRISPR library is provided. These three libraries are divided into two sub-libraries, A and B. Each library has designed three gRNAs for each gene, and also contains 1000 control gRNAs for non targeted genomes. Among them, library A has designed four gRNAs for each miRNA. The two sub-libraries can be used separately or together.
